Re: Back focusing . . . could someone please explain?

It's not deliberately designed that way.

If back focusing actually occurs, what happens is, you focus on your subject, but the sharpest area in the picture isn't the subject - what is in focus the sharpest is a little bit behind the subject.   Sometimes, one lens might have the problem on the camera, and another lens doesn't.  In that case, often all that is needed is to make a 'fine tuning' adjustment, so that the camera focuses perfectly with that lens.

If it's bad, and with all sorts of lenses, the camera could require service.  I do not believe that this is common however.
